This expression is a perfect square trinomial. It has two answers but they don't have to be different. In this case it has to be the same - because it is a perfect square trinomial.
B. The independent quantity is definitely not the words cause' of you think about it the number of words depends on the number of minutes.
Answer:
You need to use a ruler or protracter.
Answer:
last option
Step-by-step explanation:
Sin A: opp/hyp (opposite/hypotenuse)
opposite of A is 24 and the hypotenuse is 30
write that as a fraction: 24/30
simplify and it is: 4/5
Cos A: adj/hyp (adjacent/hypotenuse)
adjacent side of A is 18 and the hypotenuse if 30
write that as a fraction: 18/30
simplify and it is: 3/5
The formula for volume of a cylinder is : V = PI x r^2 x H
for both questions, plug in the known information and solve for the unknown:
Q1) V = 450, H = 8
so 450 = 3.14 x r^2 x 8
450 = r^2 x 25.12
r^2 = 450 / 25.12 = 17.914
r = sqrt(17.914) = 4.23 rounded to nearest tenth = 4.2 inches
Q2) V = 500, r=6
500 = 3.14 x 6^2 x H
500 = 3.14 x 36 x h
500 = 113.04 x h
h = 500 / 113.047 = 4.42 = 4.4 inches
